Title: Materials Data on Ce6Mg23Sn by Materials Project

Abstract

Mg23Ce6Sn crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are four inequivalent Mg sites. In the first Mg site, Mg is bonded in a 10-coordinate geometry to seven Mg and three equivalent Ce atoms. There are a spread of Mg–Mg bond distances ranging from 3.05–3.19 Å. All Mg–Ce bond lengths are 3.41 Å. In the second Mg site, Mg is bonded to eight Mg and four equivalent Ce atoms to form MgCe4Mg8 cuboctahedra that share corners with four equivalent MgCe4Mg8 cuboctahedra, edges with two equivalent SnCe6 octahedra, and faces with eight equivalent MgCe4Mg8 cuboctahedra. All Mg–Mg bond lengths are 2.96 Å. All Mg–Ce bond lengths are 3.65 Å. In the third Mg site, Mg is bonded in a body-centered cubic geometry to eight equivalent Mg atoms. In the fourth Mg site, Mg is bonded in a 12-coordinate geometry to nine Mg and three equivalent Ce atoms. All Mg–Mg bond lengths are 3.31 Å. All Mg–Ce bond lengths are 3.54 Å. Ce is bonded in a distorted single-bond geometry to twelve Mg and one Sn atom. The Ce–Sn bond length is 3.15 Å. Sn is bonded to six equivalent Ce atoms to form SnCe6 octahedra that sharemore » edges with twelve equivalent MgCe4Mg8 cuboctahedra.« less
